Lucia
A surname that often began as a medieval given name, ultimately tied to the Latin word for “light.”
The #8,217 most common surname in the United States (2010 Census) — about 1 in every 76,460 Americans shares it.
Etymology
Lucia is best understood as a surname taken from the female personal name Lucia, the feminine form of Latin Lucius, from lux meaning “light.” In medieval England and Norman records, surnames were often formed from a parent’s or ancestor’s given name, so Lucia could arise as a metronymic surname from a woman named Lucia, or as a hereditary family name derived from that personal name. The same root also produced forms like Lucius, Lucy, and related medieval spellings.
History
The excerpts show Lucia appearing in medieval English records as a byname attached to different people, which fits the normal development of surnames from personal names. Because the name is also common as a saint’s name and baptismal name, it could spread independently in several places rather than from a single family line. Later surname use is likely English and Norman-influenced, though the name is also found in wider European traditions.

Fun fact
The same ancient root behind Lucia also gave English words like “lucid” and “illuminate,” all connected with light.
